TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 481,917, dated August30, 1892.

Applicationtlednprii26,1892. seiiii No. 430,750- (Nomodel To all whom itmay concern:

Be it known that I, JOHN F. WoLLENsAK, a citizen of the United States,residing at Chicago, Cook county, Illinois, have invented a certain newand useful Improvement in Transom-Lifters, of which the following is aspecication.

The object of my invention is to make a transom-lifter which is adaptedfor use on all transoms, whether arranged to swing in or out of abuilding orroom and whether hinged at the top, bottom, or in the middle,while at the same time permitting the lifter to be attached on the frontof the casing or on either the right or left hand side thereof,dependingupon the swing of the transom. To accomplish this result, I provide acoupling or revolving joint for the lifter-arm,which is thereby free torevolve upon the guide-rod,where by the various working parts may beadapted to the above-named conditions; and my invention consists in thefeatures and details of construction hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a transom-lifterhaving a long guiderod and showing the revolving joint or couplinglocated thereon; Fig. 2, a perspective view of another form oftransom-lifter wherein the parts travel in a short guide or loop, andFigs. 3, 4, and 5 detail views of the various parts of the joint.

As the guide-rod A, lifting-arm B, set-screw C, &c., are made in theusual and well-known manner, they do not require any detaileddescription.

Referring to the form of transom shown in Fig. 1, it will be observedthat at the proper determined point on the guide-rod is secured in anysuitable manner a sleeve D,having atv its lower end a flange d and nearits upper end a small lug d. Fitting closely around this sleeve, betweenthe flange d and lug d', and adapted to rotate thereon is a collar E,provided with ears e e, which form bearings for the hinge-joint toconnect the lifting-arm The purpose of the lug and to this collar.

flange is to confine the collar and prevent its slipping up or down.

In another form of lifter, as illustrated in Fig. 2, the revolvingcoupling or joint is formed upon the sleeve which carries the setscrewC. The operation of the revolving coupling is similar in both forms oftransom-lifters. When the portion of the`transom to which the arm islinked swings in, the position of the joint is always facing, and justthe reverse when the transom swings out. Hence the Way the transomswings determines the position of the joint. It will also be observedthat the lifter can be attached either to the face of the casing or onthe inner side thereof, as desired. In the former case thehandlesupports and set-screw faces to the front and in the latter theseparts'face at right angles thereto.

What I regard as new, and desire to secure by Letters Patent, is-

l. A transom-lifter comprising a guide-rod sliding in guide-plates and alifter-arm rotatably secured to said guide rod through a swivelconnection, substantially as described.

2. In a transom-lifter, the combination of a guide-rod, a sleeve securedthereto, a collar encircling said sleeve and adapted to rotate thereon,means whereby the collar is prevented froln slipping up or down, and alift'- ing-arm secured to said collar, substantially as described.

3. In a transom-lifter, a guide-rod, a sleeve moving longitudinallyalong said rod and adapted to be locked at the proper point thereon, aset-screw to effect such locking, a collar encircling said sleeve andadapted to rotate thereon, means whereby the collar is prevented fromslipping up or down, and a lifting-arm secured to said collar,substantially as described.
